We engineer and manufacture nine column-free building systems for aviation, mining, bulk storage, logistics, sport and clean-energy infrastructure.
Every system is engineered from the ground up with distinct structural metallurgy, certified wind/snow load calculations, tailored CAD drawings, and verified global track records.
ICAO Code A–E compliant space-truss hangars for business jets, B737/A320 narrowbodies, and widebodies with full-width Megadoors.
Ground-mounted tubular steel double-lattice arch buildings. Unlimited length in 3m-6m bays. High-tension 1050g PVDF daylighting membrane for bulk storage, salt sheds & riding arenas.
Heavy Q355B tapered H-beam portal bents mounted on 4m concrete push-walls. Crane-ready (5T-30T), 100% immune to fertilizer, potash, and salt corrosion.
Hard-anodized matte 6082-T6 extruded box beam portal frames. Rust-proof modular industrial warehouses and corporate exhibition halls with double-glazed glass walls.
Warm spruce timber king poles with organic catenary curves and 750 g/m² translucent PVDF sailcloth. Engineered for winery galas, estate weddings, and cultural festivals.
Zero interior trusses. Zero support frames. Pure 1.0mm-1.5mm corrugated Galvalume steel roll-formed on-site into continuous 360° mechanically seamed arches across ground footings.
Heavy-duty tubular space-truss arches mounted between parallel ISO shipping containers. Containers act as secure side walls, tool cribs, and ballast foundations on remote job sites.
100% structural waterproofing with interlocking aluminum gutter channels, heavy Q355B hot-dip steel columns, and integrated Level 2 & DC fast-charging pedestals for commercial EV fleets.
Elongated rectangular barrel-vault pneumatic arch structures. Column-free sports stadiums, Olympic athletic arenas, and coal stockpiles up to 75m width. Dual-layer R-16 thermal membrane.
All Spanbest structures utilize standardized high-strength extruded aluminum Keder rail tensioning channels. Both PVC and PVDF membrane systems are fully interchangeable and customizable from 750 gsm to 1450 gsm across all nine building systems, benchmarked to European and North American architectural standards (Serge Ferrari Précontraint, Mehler Texnologies VALMEX FR, Sioen, Heytex).
